REINFORCED CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Application filed August 30, 1909. Serial No. 515,355.

To all whom it may concern Be it known that I, CLAUDE A. P. TURNER, of Minneapolis, in thecounty of Hennepin, and in the State of Minnesota, have invented a certain new and useful Improvement in Reinforced Concrete Construction, and do hereby declare that the following is a full, clear, and exact description thereof.

'My invention relates to reinforced concrete construction of the flat slab and column type, a type which Ihave heretofore invented and which in various forms forms the subject of an application for patent filed by me June 11, 1907, Serial No. 378,444.

In the embodiment of the invention in the aforesaid application, the capital or enlargement of the column is employed that adjoins the end side of the flat slab and as it is desiiable in certain buildings, such as office buildings, to dispense with the column capital, I have found it. necessary to invent a reinforcement having all the advantages of that which forms the subject of my above mentioned application which enables the capital to be dispensed with, and my invention, therefore, consists in the flat slab and column construction substantially as hereinafter specified and claimed.

In the accompanying drawing: Figure '1 is a vertical section through a fiat slab and a column embodying my invention; and Fig. 2 a top plan view of .the reinforcement.

In the embodiment of my invention illustrated in the drawing, the flat slab 10 and the column 11 are an integral mass or body of concrete. In the column are vertical reinforcing rods 12 which at their upper ends and within the body of the slab are extended horizontally, the extensions 14 of the rods at one side of the column being carried crosswise ofthe column toward and preferably past the rods at the opposite side of the column. The column rods having the extensions may pass entirely through the column'or they may consistof short rods only in the dipper part thereof, and as preferably constructed the horizontally extending members 14 are constructed by bending the upper ends of the rods. It will be seen that the horizontal members 14 form a head-like group or cluster and supported by the same are horizontally extending slab-reinforcing rods 15 that extend to both sides of the column into the slab in multiple directions. It will be seen that I thus get the cantaliver support without the necessity of enlarging the columns to form capltals. If desired, supplementing the horizontally extending column rod members 14, I may employ cross rods 16 running in one or more directions, and circular rods 17 that rest upon, or are supported by the members 14. c

Having thus described my invention,what I claim is:

1.. The combination of a slab and column of concrete, column rods having portions situated in the column contiguous to the slab, the upper ends of said rods being extended horizontally into the slab toward the opposite rods and reaching into the slab to points substantial distances beyond the column sides and forming a cantaliver at the top of the column, and slab reinforcement. crossing the. horizontally extending port-ions of the column rods.

2. The combination of a slab and column of concrete, column rods having portions situated in the column contiguous to the slab, the upper ends of said rods being extended horizontally into the slab toward the opposite rods and reaching into the slab to points substantial distances beyond the column sides and forming a cantaliver at the top of the column, and slab reinforcement crossing the horizontally extending portions of the column rods, said slab reinthat extend directly and diagonally above the column and cross each other thereat.

3. The combination of a slab and column of concrete, column rods having portions situated in the column contiguous, to the slab, the upper ends of said rods being extended horizontally into the slab toward the opposite rods and reaching into the slab to points substantial distances beyond the column sides, a. frame work consisting of crossed rods and circular rods supported by said horizontally extending portions of the column rods, and slab reinforcement supported by said frame work.

In testimony that I claim the foregoing I have hereunto set my hand.
